moved out of st. james palace, where he shared a suite of rooms with william, and into the newlyweds' new digs at kensington palace. and the two royals know this place well. they used to live here with their mother, diana. so, prince harry may have been acting like tom cruise in "top gun" while at training exercises in the states, flying apache helicopters, but is he now taking over the john ritter role on "three's company"? okay, he does get his own pad, so who says three's a crowd? harry and big brother, king in training william, are said to be very close. the two of them were on the phone the whole time during harry's recent trip to jamaica, heralding the queen's silver jubilee. >> he was always there as a brother, as an older brother, so therefore, wise advice, but on this trip, yes, we exchanged text messages now and then. >> reporter: and he and kate get along famously. >> to have a sister, a big sister, it's very, very nice.
